BACKGROUND Technical Field

The present technology relates to a medical, surgical and/or patient lighting apparatus, system, method and controls for use in connection with providing surgical or patient care lighting utilizing multiple wavelengths and bandwidths of pathogen killing electromagnet radiation frequencies and/or visible and ultraviolet light.

Background Description

Certain wavelengths in both ultraviolet and visible light have germicidal and bactericidal benefits for medical applications. To date, the medical industry does not use germicidal and bactericidal visible light or ultraviolet light during surgical procedures to manage surgical site infections. However, a limited application of ultraviolet light for bactericidal controls are practiced in dental medicine with small and focused emitting handheld equipment for sterilization of root canal and dental implants. The present technology uses a novel application of multiple frequencies, wavelength bandwidths of ultraviolet and visible light during surgical and medical procedures. In 2017, a group from Loyola University reported that in the United States annually, surgical site infections range between 160,000 and 300,000 at a cost of $3.5 to $10 Billion. These costs are related to additional time and care provided to the patients as hospital times are extended to treat surgical site infections. In addition to the high cost and the emotional and physical setbacks that patients suffer from acquiring a surgical site infection, it is documented that about 8,200 Americans die each year from infections caused during surgery. This pervasive problem is addressed herein with programmable lights and electromagnet radiation methods using an apparatus to kill bacteria, viruses, and pathogens in real time during surgical procedures. Various ultraviolet radiations contain wavelengths that can be carcinogenic with over exposure. In the present technology, health risks of over exposures are managed through timed or cycled radiation to administer energy levels within a safe and effective time frame and light frequency range. When electromagnet radiation is managed both for energy levels and exposure times, the use of electromagnet radiation, along with some visible light wavelengths, can kill bacteria viruses and pathogens and be safe of human exposure.

In addition to the surgical light systems light providing illumination and bactericidal benefits, the present technology is designed to use man-made ultraviolet radiation with a wavelength between 300 and 310 nm, at a safe dose rate and scheduled protocol, such that the patient's skin will synthesize vitamin D and D3 to further promote biologic healing at the surgical site.

In 2013, Buonanno, et al. reported 207-nanometer ultraviolet light as a bactericidal tool for surgical site infections. The research indicated that the 207-nanometer ultraviolet light is both safe and beneficial for humans during surgical procedures. Their conclusions were that the 207-nanometer ultraviolet light could be safe and cost effective for surgical site infection management.

Recent work by Yamono et al. (2020) indicates that direct and repetitive illumination from 222-nm ultraviolet radiation C (UVC), which is a powerful sterilizer, does not cause skin cancer in an animal model. The research also suggests that 222-nm UVC is safe for human eyes and skin. The ultraviolet radiation of 222 nanometers has similar antimicrobial effects compared with radiation of 254 nanometers that is known to have human health risks and is considered to be carcinogenic.

Visible light is used in the present technology and provides both illumination and bactericidal effects. Blue light in the spectral range of 407 to 470 nanometers (frequency (749-599 terahertz) is known to kill various pathogens. Other visible light wavelength bandwidths in the 488 to 514 nanometer (frequencies 614-583 terahertz) range also kills various bacteria and higher bandwidths around 630 or 780 nanometers (frequencies 475-384 terahertz) are also utilized to kill certain bacteria, viruses and pathogens during application in the medical and dental practice. Each wavelength in both the ultraviolet range and the visible light range are combined into a lighting and radiation system that is programmed to be safe for human use and provide bactericidal functions.

Additional ultraviolet and visible lights are known to kill airborne microbial diseases.

While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned devices or systems do not describe a medical lighting apparatus, system, method and controls that utilize a 200 to 222 nanometer wavelength as one of many ultraviolet wavelengths integrated into a programmable lighting system for managing or killing surface and airborne pathogens or diseases in medical use during surgery or dental procedures.

A need exists for a new and novel medical lighting apparatus, system, method and controls that can be used for managing or killing surface and airborne pathogens or diseases in medical use during surgery or dental procedures. In this regard, the present technology substantially fulfills this need. In this respect, the medical lighting apparatus, system, method and controls according to the present technology substantially departs from the conventional concepts and designs of the prior art with the use of a fully integrated lighting and pathogen destruction electromagnet radiation system. In doing so provides an apparatus primarily developed for the purpose of managing or killing surface and airborne pathogens or diseases in medical use during surgery or dental procedures.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. to provide a thorough understanding of the present technology. However, it will be apparent to one skilled in the art that the present technology may be practiced in other embodiments that depart from these specific details.

Frequencies at a designed and employed energy level in both ultraviolet and visible light have germicidal and bactericidal benefits for medical applications. The present technology is novel because it provides multiple frequencies, wavelengths or bandwidths of ultraviolet and visible light for illumination and pathogen killing electromagnetic radiation are all part of the integrated lighting system that are used during a medical procedure or surgery. The apparatus is designed for use as a safe bactericidal system using electromagnetic radiation in selected frequencies on a programmed scheduled energy and timed dose that uses a method and apparatus for optimal health benefits. Furthermore, it reduces the risk of surgical site infection for the patient. The multiple electromagnetic radiation frequencies and bandwidths are controlled separately through computer programming to provide safe and effective timed dose of the specific electromagnetic radiation with selected frequencies at a programmed or set energy level. The control programming may be cycled on and off over a time period to optimize the health benefits and minimize harmful effects of radiation. The present technology has the capacity for use in real time during a surgical or wound care procedure to reduce surgical site infections by using several spectrums of visible and ultraviolet light and their associated frequency ranges to kill pathogens and microorganisms.

In addition to use during surgical or emergency medical procedures, the apparatus and methods have an equal value for patient care in postoperative patient care. The combined use of the invention during real time surgical procedures and during follow-up care has potential to reduce surgical and wound infections. Surgical site infections prolong the patient's hospital stay on an average of over nine days which substantially increases the cost of patient care.

The present technology may also include the health benefits related to pre-vitamin D synthesis from ultraviolet radiation. The present technology is designed to promote healing by using the medium wavelength ultraviolet radiation as a growth stimulus for cells, tissues, and bones in animals, specifically, humans. The invention uses a combination of light emitting diodes (LED) and specialized gas vapor bulbs as a medical tool and treatment to produce a wavelength of the radiation is within the ultraviolet range of 300 to 310 nanometers. This radiation range is equivalent to the ultraviolet-B sunlight and is responsible for production of vitamin D in the human skin. Vitamin D is vital to life and has been associated with many health benefits.

Light skinned humans adsorb ultraviolet-B sunlight at a rate approximately five times faster than dark skinned humans. Skin color is a factor in treatment when using 300 to 310 nanometers ultraviolet radiations that is generated by specialized lighting equipment and bulbs. This frequency range of 999 to 967 THz at the correct dose will not damage or kill cells as the energy level and time of exposure is programmed and controlled to be safe and healthy.

The apparatus, methods and controls that are used in surgical lighting also provide real time safe bactericidal advantages over lighting that only provides illumination. The present technology is novel over surgical lighting by providing multiple wavelengths or multiple bandwidths of visible light for constant illumination of the surgical field as well as programmable electromagnetic radiation at human safe energy levels to deliver focused and managed doses of bactericidal radiation during a medical or surgical procedure and postoperative patient care. The surgical and patient care lighting system operates with exposure levels that are harmless to humans and lethal to harmful pathogens that cause infection and retard healing. The programmable light and electromagnetic radiation doses, i.e. energy level and time of exposure, are delivered on a scheduled basis, typically three or more short dose exposures of 1.448 PHz frequency for a surgical procedure or for entirely harmless pathogen killing electromagnetic radiation, that would be delivered to the target area on a scheduled dose, or blue light in the spectral range of 749 to 637 THz that can have scheduled doses or can remain on safely throughout the surgical procedure. The dose to kill bacteria, viruses, microbes, or parasites may range from less than a second and, typically, up to several seconds which is delivered pre-, intra- and post-operatively. This safe bactericidal practice uses electromagnetic radiation on a scheduled energy and timed dose in a method and apparatus for optimal health benefits and reduction or potential elimination of surgical site infection for the patient. The electromagnetic radiation frequencies that are used during the medical procedure and the dose of the electromagnetic radiation are managed to be harmless to the patient and lethal to bacteria, viruses, and parasites. The delivery of the pathogen killing lighting is achieved by focusing the bean of radiation through a fused silica lens. These lenses will need to meet the specifications and objectives of a pathogen killing overhead surgical light system. The specific fused silica lenses that are commercially available may not meet the special design criteria for use in the present technology. However, the technology to build these lenses exists and commercial lens companies can be contracted for specialty lens production. The design specifications for the surgical lighting system will be based on delivery of electromagnetic radiation as a selected dose to the target area surgical site from an overhead or portable lighting equipment. For example if the overhead lighting system is 180 centimeters above the patient's surgical site, the focusing lens may be employed to project 20 millijoules over a ten second period of electromagnetic radiation with frequencies 1.489-1.350 PHz, and 999-967 Hz. in an area of a circle that is 20 centimeters (an area of 314 square centimeters). The energy level of the electromagnetic radiation is engineered, scheduled and programmed to meet the pathogen killing objectives and be entirely harmless to the patient, surgeon and medical staff.

Buonanno et al. (2013) previously reported 207 nanometer ultraviolet light as a bactericidal tool for surgical site infections. The research indicated that the 207-nanometers ultraviolet light (electromagnetic radiations with a frequency of 1.448 PHz) is both safe and beneficial for humans during surgical procedures.

Buonanno et al. (2017) published a follow-up study that presented the used ultraviolet C light in the range of 200 to 222-nanometers. The researchers selected the UVC light because of its limited penetration distance into biological samples and are basically lethal effect on several bacteria but do not damage cells or tissue. The 200 to 222-nanometer UVC wavelength has a similar cidal effect on pathogens to a 254-nanometer wavelength UVC light. UVC light with 254-nanometes is known to kill around 60 pathogens with does from a fraction of a second to just over nine minutes, however the 254-nanometer light is not safe for human exposure and is therefore typically used in bactericidal application that are enclosed and not available for human exposure, such as enclosed heating and air-condition systems.

The wavelength of the visible or ultraviolet light, such as 200 nanometers, is a dimensional description of the peak to peak sinusoidal wavelength that is emitted by solar energy or manmade equipment. The photon energy (eV, aJ) is an additional criteria used for electrical engineering system for a given visible or ultraviolet light. An electron-volt (symbol eV) is the amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt in vacuum, and aJ is an energy expression where one attojoule=10⁻¹⁸ joules.

For example, ultraviolet C light with wavelengths between 100 and 208 nanometers has photon energy of 4.43 to 12.4 electron volt (eV): 0.701 tp 1.987 aJ. In addition, the visible and ultraviolet light has a frequency that utilizes the energy through vibration at a certain cycle, such as 200 to 222 nanometer ultraviolet radiation has a frequency between 1.489 and 1.350 PHz. These are significant criteria when calculating the pathogen destruction engineering and design for a surgical or medical procedures light system. With respect the biological criteria and the biomedical and biomedical-engineering design of the pathogen killing visible and ultraviolet surgical and medical procedures lighting system utilizes the relative size difference of a human cell that is typically 10 microns. In contrast harmful pathogens such as bacteria are typically less than one micron and viruses are in the size range around 100 nanometers. So human cells, that need to be protected and preserved are in general 10 to 100 time larger and unaffected by the design dose of selected electromagnetic radiation light that kills the harmful pathogens that are targeted by the lighting system in the present invention. In conclusion, the frequency vibration and the energy applied by the selected electromagnetic radiation with frequencies 1.489-1.350 PHz and/or 999-967 THz in the ultraviolet spectrum and with frequencies 749-637 THz, 614-583 THz, and 475-384 THz in the visible light spectrum for pathogen destruction kills the pathogens are harmless to human cells that are typically one or more magnitudes larger than pathogens. Hence, electrical, mechanical, and biomedical engineering as applied to the apparatus, systems, methods, and computer controls affords the present invention novel status. By knowing the targeted pathogen population and destruction criteria, the lighting system design and manufacturing, as used in a surgical or medical procedures setting, can safely achieve scheduled pathogen destruction with doses of effective energy and time periods while preserving healthy human cells and optimum patient health. The present invention, in a non-obvious manner, employs multiple disciplines of engineering, science, and design to invent a novel integrated surgical and medical procedure lighting system that is effective for pathogen destruction and safe for human use to reduce or eliminate surgical site infections.

The present technology uses light for illumination in combination with programmable electromagnetic radiation frequencies that provide scheduled doses of the various frequencies both for energy levels and timed exposure for safe use and concurrent health benefits. Considerations for individual patients based on their skin coloration and tone can be programmed into the lighting and radiation system to safe exposure levels at an optimum dose. The Fitzpatrick skin table that uses six categories for color from 1 very light skin to 6 very dark skin may be used when programming the lighting and radiation equipment to ensure safety for all persons exposed to the equipment light and radiation. A motion detector in the lighting system will turn off all wavelengths that could be harmful to humans or animals.

The visible light that is used in the present technology provides both illumination and bactericidal benefits. Blue light in the spectral range of 407 to 470-nanometers with a frequency range of 749 to 637 THz is known to kill at least 26 known pathogens such as gram-positive Streptococcus thermophiles and methicillin resistant Staphylococcus aureus (MRSA), which relates to a cost of 2.3 to 4.2 billion dollars per year as hospital expenses for the MRSA infection management.

Ultraviolet light at 207-nanometer (frequency 1.448 PHz) will be safe and cost effective as a supplemental tool for surgical site infection prevention, in addition to per-operative antibiotic use. The 207-nanometer wavelength is one of the ultraviolet wavelengths that is utilized it the present invention's programmable lighting system for medical use during surgery or dental practice to manage surgical site infection with the use of germicidal, bactericidal, and virus control of harmful microbes. The present technology uses light for illumination in combination with programmable electromagnetic radiation frequencies at selected energy levels to provide scheduled doses of the pathogen killing radiation with energy levels and timed exposure for safe use with multiple healthy benefits.

Selected electromagnetic radiation as used as used in the present invention during intra-operative and post-operative care can kill bacteria, protozoa, viruses, and yeast in relatively short periods of time, typically measured in seconds. The electromagnetic radiation frequencies, energy level, and time of exposure are assessed to be effective in destruction of harmful agents, while also being managed to be harmless to patient. Microorganisms quickly absorb ultraviolet-C radiation which destroys the microbe's DNA, typically in time periods that are insignificant to human health. Some microbes are killed in less than one second, while other forms of bacteria, protozoa and viruses can take up to several minutes to kill depending on the frequency and dose of electromagnetic radiation. The present technology's primary function and purpose is the care, health, and wellbeing of each patient. As such, apparatus, methods, and electronic controls used in the invention limit adverse effects to a patient by limiting the dose of visible and ultraviolet light radiation along with a factor of safety to ensure no harmful impact to a patient's tissues or organs that benefit from the death and destruction of harmful pathogens.

The use of the spectrum of radiation of visible and ultraviolet light as generated by the sun available for use in the present invention lighting system that is managed by the computer-controlled method, apparatus, and system to provide safe and effective health benefits for humans and other applications. The method, apparatus, and system may include use without human exposure for bactericidal, germicidal, virus and pathogen destruction in vacant rooms as a pre-operative sterilization method. A motion detection sensor will allow the system to shut off or reduce the light and radiation for safe and beneficial human exposures of the various wavelengths.

The present technology is intended for focused application of selected electromagnetic radiation frequencies for use within surgical fields as a bactericidal and germicidal system that reduces or eliminates surgical site infections.

Some aspects of the present technology can include apparatus, methods, and controls that can be used as surgical or medical procedure lighting that provides illumination with the use of multiple LED or halogen bulbs or other safe and bright lighting sources across the entire ultraviolet spectrum and visible light spectrum. The light system can provide illumination for surgical or medical procedures and also provided pathogen killing benefits when the electromagnetic radiation is delivered using a fixed or adjustable focused beam and energy levels of the managed dose or doses of bactericidal, germicidal, and antimicrobial radiation during a medical or surgical procedure. The present technology can be programmed to project a light source for surgical site or medical procedures illumination, human safe pathogen killing electromagnetic radiation. The pathogen killing radiation can include the first electromagnetic radiation frequencies of 1.489-1.350 PHz, and frequencies 999-967 THz and the second electromagnetic radiation frequencies of 749-637 THz, 614-583 THz, and 475-384 THz; all within the suite of lights and electromagnetic radiation that are used in the present technology; or select sets of electromagnetic radiation frequencies may be chosen to meet surgical and pathogen killing objectives. The pathogen killing electromagnetic radiation utilized in the present technology is safe for human and animal use and can be programmed by a computer or manually controlled by a technician where the surgical site infection management lighting system uses one or more visible and safe colored laser beam(s) so that the operator can visually adjust the focused radiation sources to be aimed at a surgical or medical site during the surgical or medical procedure and can also be used in veterinary medicine.

Some aspects of the present technology can include be used in a surgical procedure or post-operative care where the objective is to kill bacteria, viruses and other harmful pathogens, such as fungus, protozoa, yeast, et cetera, where a certain suite of pathogens that are targeted to be killed and destroyed by a scheduled dose of electromagnetic radiation with a fixed frequency or frequencies. The doses of electromagnetic radiation are harmless to patients and medical providers and the following example provides one type of use of the invention. A hypothetical scenario for use of the present technology can be a patient undergoes a laparotomy surgical procedure where the surgical incision on the patient is 12 centimeters long and two additional centimeters are added to give sterilization margins. Beams of pathogen killing electromagnetic radiation will be focused to have a 14-centimeter diameter, with an area of 154 square centimeters where the focal length and energy level of each of the selected electromagnetic radiation are projected from a ceiling or wall mounted lighting system that may be 180 centimeters above the surgical site. The beam or beams of electromagnetic radiation will be limited to the precise area of the surgical site, and will only be projected on a scheduled basis to meet objectives destroying pathogens and thereby reducing or eliminating potential surgical site infection. Engineering and design practices will be used to ensure that the proper dose of electromagnetic radiation is projected to the surgical site.

The present technology can be used to kill 99% of pathogens known to be destroyed with electromagnetic radiation frequencies of 1.489-1.350 PHz with no adverse effects on human skin or the human eye and could be used to achieve the objectives of the present technology. The ultraviolet light dosing would be dependent on the actual time of the medical procedure, where the actual surgical procedure dose could be one 12.5 seconds each and would provide a 10 millijoule dose. Several doses over the length of the surgical procedure at the same level may be used during the medical procedure. A post-operative dose could be delivered as a final closing step. All electromagnetic radiation doses will be configured to be safe and harmless to the patient. This electromagnetic radiation at the prescribed energy level and time will typically kill around 30 harmful pathogens. Table 1 below shows a hypothetical scheduled for the use of frequencies 1.489-1.350 PHz for pathogen destruction.

TABLE 1 Electromagnetic radiation for pathogen destruction using the frequency range between 1.498 and 1.350 petahertz Radiation power: Radiation Phase of Scheduled per sec. in time Lethal dose for a select set of procedure radiation microwatts in sec. 30 pathogens is 10 mj per cm² Pre-incision at 18 min. 800 12.5 10,000 microjoules = 0 to 20 minutes 10 millijoules per cm² Intra-operative at 25 min 800 12.5 10,000 microjoules = 21 to 120 minutes 10 millijoules per cm² at 60 min. 800 12.5 10,000 microjoules = 10 millijoules per cm² at 115 min. 800 12.5 10,000 microjoules = 10 millijoules per cm² Closure of incision at 130 min. 800 12.5 10,000 microjoules = 121 to 140 minutes 10 millijoules per cm²

During the surgical procedure electromagnetic radiation frequencies in the range of 1.498 and 1.350 PHz can be used with 800 microwatts power for 15 seconds delivered to the surgical site that will provide sufficient pathogen destruction. Using an extra 2.5 seconds of time, i.e. 15 seconds rather than 12.5 seconds, ensures complete pathogen destruction at the surgical site, while still being safe for human use because the radiation frequency range of 1.498 and 1.350 PHz is known to be harmless for human use in low doses. The total electromagnetic radiation frequency range of 1.498 and 1.350 PHz will be 800 microwatts multiplied by 15 seconds, which provides an engineered factor of safety of about 1.2 and will deliver 12,000 microjoules or 12.0 millijoules per square centimeter of pathogen killing radiation. Each of the five doses will kill 99% of the targeted pathogens each time and will be safe for human exposure. Electrical engineering, mechanical engineering, biomedical engineering, and computer programming is utilized to ensure the correct energy level and dose time are designed and delivered to the surgical site for optimal patient health and healing.
